If you want to upgrade or replace your laptop hard drive, you want to make sure you get one that’s the best fit for your particular laptop, and if you’re not a pro at these sorts of things, make sure you know all the facts before investing in a new hard drive and start taking your laptop apart (we’re talking about an internal hard drive here – check out this post for external hard drives).

So what do you need to know? Here are the main points to consider (for once, we’re not concerned with whether they come in pink or not, since they won’t be visible anyway):

Capacity
Traditional rotating laptop hard drives come in sizes from 20GB to 1TB, and Solid State Drives (SSD) for laptops are available in 8GB to 1TB. Solid State Drives can handle being shaken and dropped, and do not spin, so rpm is not a factor here. Price is though – they are expensive. A 1TB SSD drive costs around $3,000-$4,000+ whereas a Western Digital 1TB hard drive (5400rpm) is around $180! Also, on newer laptops you should be fine installing an SSD, but if your laptop is older and runs on XP, the operating system is not optimized for an SSD and you may experience difficulties with it.

RPM
RPM stands for Revolutions Per Minute and tells you how fast your hard drive spins. 5400rpm is the most common speed in laptop hard drives, but they come in 4200, 7200, 10000 and 15000rpm as well (the two larger numbers are for hard drives you buy separately, there are no laptops on the market with that kind of HDD already installed, not even gaming laptops). The faster they spin, the faster your system operates. However, spinning fast also means consuming more energy (draining the battery) and generating more heat, so that’s something to consider.

Physical Size
This one is obviously very important. Laptop hard drives come in two standard sizes – 1.8″ and 2.5″, with the 2.5 hard drive being the most common. You’ll find the 1.8″ mostly in mini notebooks. However, they also come in different thicknesses. A 12.5mm hard drive will not fit in a laptop that has a 9.5mm slot. Check your manual or call the manufacturer to make sure you know what your laptop needs.

Interface/Connector
Interface means how your hard drive communicates with your laptop and there are two different kinds: SATA (serial ATA) and PATA (parallel ATA a.k.a IDE). You can tell which is which by looking at the hard drive pins – PATA extends out from the body of the hard drive whereas on SATA drives, the pins are more a solid part of the drive. There are also two types of connectors: IDE and ZIF. Check your documentation to see which one your laptop uses.

Cache
The cache is a space on the hard drive that stores data temporarily for fast retrieval. A larger cache can improve the speed of your system, but it’s not the most important factor (rpm is when it comes to speed). In fact, if you go to some of the major manufacturers’ websites and look at the specs for the laptops, the size of the hard drive cache is not even listed. It is though if you’re buying a separate hard drive to install yourself. 8, 16 or 32MB are standard cache sizes.

So is a 750GB 5400rpm hdd better than a 500GB 7200rpm hdd? Better is not the right word: the first drive will store more but be a bit slower and the second drive will store less but work faster. You have to decide what’s most important for you and base your choice on that.

Dell’s Studio 14z is their lightest and most slim Studio laptop to date, measuring 13.23 x 0.79 x 9.02″ and weighing in at 4.30 lbs. It comes in 6 colors, Promise Pink is one of them, and as always, Dell donates $5 of the sale price of their pink laptops to Susan G. Komen for the Cure.

The 14z comes with some really nice extra features like face recognition and theft prevention (the full list can be found further down in this post) and has gotten rave reviews.

It comes in 3 slightly different configurations, which can all be customized. The least expensive version is $649 (+$40 to get it in pink) and features:

• Windows Vista 64-bit Home Premium Edition operating system
• 2.0GHz/800Mhz FSB/1MB cache Intel Pentium Dual Core T4200 processor
• 14.0″ HD (720p) display (with built-in 1.3MP webcam)
• 250GB 5400RPM SATA hard drive
• 3GB dual channel DDR3 memory at 1066MHz
• Wireless 802.11g Half Mini Card
• NVIDIA® GeForce® 9400M G (graphics and chipset)
• 6-cell 56Whr Li-ion battery

The top-of-the-line optional upgrades available for the basic model are:

• 5GB DDR3 at 1066Mhz memory ($275)
• 2.66GHz/1066Mhz FSB/6MB cache Intel Core 2 Duo processor ($350)
• Windows Vista Ultimate Edition operating system ($150)
• 500GB 7200RPM SATA hard drive ($175)
• 14.0″ HD+ (900p) bright LED display ($50)
• Dell 1515 Wireless-N Mini-card ($25)
• AT&T built-in cellular mobile broadband ($125)
• Dell Wireless 365 Bluetooth Internal ($20)
• 8-cell 74Whr Li-ion battery ($40)
• ExpressCard Sound Blaster X-Fi Laptop Sound Card with Wireless Receiver Bundle ($130)
• Back-lit keyboard ($25)

So if you went with all the top choices for this system, you would end up with a price tag of $2,054.

One important thing to note is that these computers do not come with internal DVD or CD drives, so you have to get an external one if you want to use that kind of media.

The most expensive version of the Studio 14z sells for $799 (+$40 for pink), and comes with:

• Windows Vista 64-bit Home Premium Edition operating system
• 2.1GHz/800Mhz FSB/2MB cache Intel Pentium Dual Core T6500 processor
• 14.0″ HD (720p) display (with built-in 1.3MP webcam)
• 500GB 5400RPM SATA hard drive
• 3GB dual channel DDR3 memory at 1066MHz
• Wireless 802.11g Half Mini Card
• NVIDIA® GeForce® 9400M G (graphics and chipset)
• 6-cell 56Whr Li-ion battery

The top-of-the-line optional upgrades available for this model are:

• 5GB DDR3 at 1066Mhz memory ($275)
• 2.66GHz/1066Mhz FSB/6MB cache Intel Core 2 Duo T9550 processor ($300)
• Windows Vista 64-bit Ultimate Edition operating system ($150)
• 500GB 7200RPM SATA hard drive ($75)
• 14.0″ HD+ (900p) bright LED display ($50)
• Dell 1515 Wireless-N Mini-card ($25)
• AT&T built-in cellular mobile broadband ($125)
• Dell Wireless 365 Bluetooth Internal ($20)
• 8-cell 74Whr Li-ion battery (lasting up to 6.5 hours) ($40)
• ExpressCard Sound Blaster X-Fi Laptop Sound Card with Wireless Receiver Bundle ($130)
• Back-lit keyboard ($25)

If you added all the top choices for this system, you would end up with the same computer and a price tag identical to the one above: $2,054.

The only differences between the two basic configurations are the processor and hard drive, and if you were to upgrade the least expensive basic model to match the most expensive one, you end up with the exact same price ($799).

Extra features on the Studio 14z include:

• 3 USB ports (one of which is an eSATA port)
• 4-watt 2.0 SRS audio (great speakers!)
• Online backup service (Dell’s own)
• Remote access (lets you access what’s on your home computer and other electronics remotely)
• FailSafe theft prevention (which allows you to erase files, lock the computer, and track the ISP location of your laptop when the thief connects it to the internet)
• Facial recognition (to prevent others from logging in)

Also, Dell offers a free Windows 7 upgrade, and as someone who has battled with Vista for a few years now, I’d jump on that offer! For more current deals on Dell (and other) laptops, check out my “Deals, Extras and Offers on Pink Laptops” post.

As a follow-up to my Dell Inspiron Mini post, I thought we’d take a look at how Acer’s Aspire One compares to Dell’s Mini 9. I’m comparing it to the least expensive, basic configuration of the Mini, since that is the model most similar to the Aspire One.

The Aspire One is available in two display sizes: 8.9″ and 10.1″, but only the 8.9″ comes in pink. It’s what I would call a “happy shade of pink”, Acer calls it Coral Pink: either way, it’s very pretty. It’s not customizable, but you can find a few different configurations online.

Below are the specs for the most widely available system. I have listed the same specs, in the same order as for the Dell Minis for easy comparison:

Operating System: Windows XP Home Edition
Processor: 1.6GHz/533Mhz FSB/512KB L2 cache Intel Atom
Screen: 8.9″
Hard drive: 160GB SATA
Memory: 1GB (512MB onboard, 512MB SO-DIMM)
Wireless: 802.11b/g
Graphics: Intel GMA 950
Battery: 3-Cell Lithium-Ion (optional 6-Cell Lithium-Ion)

Size: 9.8 x 1.1 x 6.7″
Weight: 2.19 lbs with the 3-cell battery, 2.78lbs with the 6-cell
Cost: $299.99

So how does this compare to Dell’s Mini 9 apart from the different operating systems (Windows XP vs. Linux)?

Similarities

• The processor, screen size, wireless and graphic cards are the same.
• Neither one comes with an internal CD/DVD drive.
• The price, size and weight are almost exactly the same.

Differences

• The battery options do differ a bit, a 4-cell is the only option on the Mini, whereas on the Aspire One, you have the option of upgrading to a 6-cell.

• The Aspire has more memory (although you are able to upgrade the Mini to 2GB for $75).

• The hard drive is where you see the big difference: Aspire One’s 160GB (SATA) vs. Dell’s 4GB (solid state). You can upgrade the Mini to a 32GB SSD (for $100), but it’s still smaller. Having said that, if your laptop has to endure a lot of shaking and the occasional drop, you’re better off with a solid state drive.

On a separate note: Tomorrow, April 7, Acer is having a huge event in NYC, where they will be launching five new product lines. I don’t know yet if any of them will be pink, but stay tuned! Update: Acer did announce several new notebooks and a nettop PC but nothing in pink.
